SPECIFICATION forming part of Letters Patent No. 433,135, dated July 29, 1890.

Application tiled May 9, 1889. Serial No. 310,083. (No model.)

Zh all whom t may concern:

Be it known that I, ORRIN B. PECK, a citizen of the United States, residing at Chicago, Illinois, have invented certain new and useful Improvements in Apparatus for Use in Decomposin g Metallic Salts and Desulphurizing Ores, of which the following' is a specification.

The object of my invention is to improve an apparatus for mechanically decomposing chemical compounds, metallic salts, or salts of metals, and desulphurizing ores or their resulting material, when the substances treated are in a molten condition, by the action of-centrifugal force; and my invention consists in the features and details of construction h'ereinafter described and claimed.

In the drawings, Figure l represents a vertical longitudinal section of my improved apparatus with the running-gear in elevation. Fig. 2 represents a plan view taken on the line 2 of Fig. l. Fig. S represents a plan view taken on the line 3 of Fig. l. Fig. 4 is a plan view of the mouth of the receiving-vessel shown'in Fig. l. Fig. 5 is a vertical section of the mouth of the receivingyessel somewhat modied, and Fig. is a plan view of such modiiication.

In making my improved apparatus for decomposing chemical compounds, metallic salts, or salts of metals, and desulphurizing ores I make a receiving-vessel V, constructed and adapted to receive the substance to be treated when in a molten condition. The re` ceiving-vessel may be made in such a way as will secure the required strength and reduce the conduction of heat from the interior to the exterior, and in other respects so made as will he calculated to subserve the end in view and permit of its being rotated at a high rate of speed for the separation of particles of different degrees of density in the m atter treated. Many of these parts and the details ot their construction do not form the special subjectmatter of my claims, and need not be more fully described, as they will h'e suliiciently understood from an inspection of the drawings. The receiving-vessel is arranged to he supported on an actuating-shaft A, which is intended to be connected with the power of the works and rotated at a high rate of speed. The receiving-vessel is provided with a lining, preferably made of cast-iron, and of an exterior size and shape adapted to be inserted in and removed from the outer shell or case of the receiving-vessel. I make the lining, however, of more than one piece, and preterably of two pieces divided vertically. These two pieces, if two be used, are intended to have a small space left between their edges, so that there will be, as it may he termed, a crack or open slit from the bottom to the top on different sides of the lining. These cracks or slits are intended to permit the lining to expand when subjected to the great heat of the molten material intended to be treated in contact with it. By reference to Fig? 2, which is a plan view of the section of Fig. l, taken on the line 2, the cracks or slits will be clearly shown. To cover these cracks or slits and prevent them from being filled with the molten material treated, and also to assist in holding the parts firmly together, I employ a covering strip or plate B, extending from the bottom to the top of the lining and of suiiieient width to cover and protect the crack from the material treated.

In order to hold the portions of the lining in their proper position with reference to the outer shell or case of the receiving-vessel, I pass bolts C through the strip or plate B and through the crack or slit in the lining, and fasten them with nuts on the outside of the shell or ease, as shown in the drawings. Bolts may also be inserted through holes made in the lining at other places than at the cracks or slits that I have shown in Fig. 3. \Vhere such bolts are used, they should preferably be arranged at that place where they willleast interfere with the expansion of the lining ofthe receiving-vessel, and

in Fig. 3 I have shown them arranged midn way between the opposite cracks or slits. In Fig. 3,which is a plan view of a section of Fig.

l, taken on line 3, I have shown the strip B 9 as provided with projecting bosses D, fitting into holes made in the lining at the point where the bolts C are intended to be passed through. These bosses assist in holding the strips in place and in strengthening and se- IOC curing the parts. I prefer, also, to make the lining of the receiving-vessel slightly shorter than the distance between the top of the outer shell or case of ,the receiving-vessel and its bottom, as shown at E in Fig. l, to permit vertical expansion of the lining when subjected to heat. The upper portion of the lining is preferably provided with a separate and removable piece F, which is also preferably somewhat smaller in diameter than the space in which it is placed, so as t0 leave room for expansion at Gof Fig. l. The lining for the neck or mouth of the receivingvessel is preferably made with vertical recesses or channels, dovetailed in shape, so that dovetailed blocks II, with channels in their faces, may be inserted into them. The

channels in the faces of the blocks are intended to be slightly deeper than the interior surface of the neck or mouth, so that the material rising to the neck or mouth of the receiving-vessel lby the action of centrifugal force will be discharged through these channels rather than over the surface of the neck or mouth. These blocks are preferablymade of material capable of standing the heat and wear to which they are subjected, so that they Will last as long as possible, and are eX- tended slightly above the top of the neck or month, so that the discharging material is -kept from contact therewith. As they become worn they may be removed and other channeled blocks inserted in their places. In Figs. 5 and 6 I have shown a modification of this idea by providing a channeled rirg I, vthat may be inserted and removed, instead of the channeled blocks. The use and operation of this channeled ring are the same the channeled blocks, and need not be described more minutely in detail.

In Fig. l I have shown a space between the outer Wall of the receiving-vessel and the annular tub J, which catches the material discharged from the receiving-vessel, and from which it may flow or be removed in any desired manner. The annular space may be designated by K, and is covered by a removable annular ring or plate L. One object of thus providing this covered space is to permit Water to be introduced therein from a pipe or other convenient means to assist in cooling the receiving-vessel or preventing-its becoming overheated Whenin operation. The cover L also prevents any of the material discharged from the receiving-vessel `from falling into this space and interfering with the operation of the vessel or the cooling action 0f the Water. When it is desired to remove the receiving- Vessel it may be lifted off out of the Way. The inner edge of the plate or cover L is preferably fitted around the neck or mouth of the receiving-vessel in such a Way as to rotate with it, and thus force the material falling on it to pass ou out to the receptacle provided for it, and it is therefore shown not attached to the annular tub or other parts.

What I regard as new, and desire to secure by Letters Patent, is-

l. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores When in a molten state, the combinat-ion of arevoluble receiving-vessel adapted to receive molten material to be treated, a neck or mouth having an opening for the discharge of the molten material and provided With grooves or channels in and along the sides of the opening and parallel therewith, throughwhich the molten material flows in discharging, and means for revolving said vessel, substantially as described.

2. In an apparatus for decomposing metallic salts or salts of metals and desulphurizing ores when in a molten state, the combination of a revoluble receiving-vessel adapted to receive molten material to be treated, a neck or mouth having an opening for the discharge of the molten material and provided with one or more removable blocks arranged in and along the sides ofthe opening and parallel therewith and having grooves or channelstherein through Which the molten material flows in discharging, and means for revolving said vessel, substantially a's described.

3. In an apparatus for decomposing metallic salts or salts of metals and desulphuriz ing ores when in a molten state, the combination of a revoluble receiving-vessel adapted to receive the molten material to be treated, a removable revoluble annular ring or plate extending out around the neck or mouth of the receiving-vessel,and means for revolving said vessel, substantially as described.
